What Kind Of Oil For An N14

It seems like n14 does not care about the oil brand, but I personally like Rotella

 

You still leased to Landstar?

 

How many miles? Find out what’s in the engine now, I’d stick with whats working!

 

If I remember correctly, My 95 KW with a 435/1650 Celect N-14 had a Delvac recommendation sticker on it when I bought it new. I don't remember if I stuck with the same oil the whole time I owned the truck. It was an outstanding motor! Embarrassed many 500 Cats with it!

I run valvoline blue now, she didn’t like rotella after the inframe

 

My T2000 KW with N14 ran Delvac, I swapped to Schaffer 15-40, no problem at 965k miles no inframe.

 

The only brands I've seen a difference is traveller (tractor supply) and farm rated (fleet farm) the motor uses an extra gallon per 12,000 miles.
I do oil samples every change with similar results. I've used all brands, now I mostly use citgo semi-synthetic because that's what the mechanic stocks.

 

Walmart Super Tech,,,hey, don't laugh, it's the #1 selling automotive oil, repackaged Quaker State, no foolin'. For a Cummins, I ran Rotella, a choice most companies I drove for recommended if adding on the road. Once, I added Delo on the road, told the boss, he immediately brought the truck in for an oil change.
